Stock piston with 1.1 drilled up holes

As I suspected...

Why is it had to be drilled? Just need to know of what 0.1 mm can make a difference? I still use the stock piston yet it still feels no difference. That is for me though.

bigger piston hole allow faster response from the shock

Someone who can tell my how to balance my car. On xray there is to small holes in the bottom, one in rear and one i front, where you can put the car on spikes. But I can't see how on my BD5WXi kit.

How do you guys find out where to put weight to get it in balance ?

rai

It is not precise but it is worth to place the weight where it should be. What i did was put two allen wrenches just under the shock towers front n rear respectively. Make sure you put your wrenches right at the center of the towers. Carefully lift the car and wallaaa.. U know where to add the weight on your car. Oh by the way make sure esc n battery are strapped on the chassis.

Dont get it. It cant be such a big effort for Yokomo just too machine two holes under the chassi....

And by using electronic balances? 2 or 4 one needs?
( I have identical two of it in 1/10 of gram) is it for the tweak only or it also works to balance the chassis please?

rai

Then it would just be the same as other brand. hehehe

You may want to try that but I have used this method before. It is very frustrating and tiring of course. Every time you adjust one side of the car then the weight changes on the other three sides. You adjust another side, then the side you have just done adjusting changes. It keeps on changing once you tampered one side of the car. So it is up to you to try it.

alright, thanks for you answer

can I try first with only 2 balances ?

Do I adjust with adding weight or using spring tension ( like told in X ray Set up Book) please?

rai

I think you can try first with 2 electronic balances however, as said everywhere it is all about weight transfer i.e. left and right & front and rear.

Usually I balance my car first then tweak it as said on the guide book.

Nico'

there is something I don't understand, I thought that tweak was a way to balance the car.
according to you, balance and tweak are 2 different thinks?

you balance with adding weights please?

"Weight Balance
You should always try to adjust the weight on your car so it is equal front/rear and equal
left/right. This will help to ensure proper, consistent handling. You can use balancing tools
to check the weight distribution of your car, and to ensure that your ready-to-race car
does not list to one side or one end.
31
Examples of balancing chassis weights (front, rear, center)
A simple balancing tool can be a set of stands with points on them. You would then
place the chassis on the points of the stands so that the stand are along the car’s
centerline at the front and rear. If the car lists to one side (for example, to the left), add
weight to the other side (say, to the right) until the car stays level when left untouched.
You can do this also to check front/rear balance by putting the chassis on the balancing
stands on the left and right sides half way along the length of the chassis." - taken from the set up guide that of hudy.

From this I assume adding weight and tweak are two different things.

Thanks a lot,

I found what you wrote page 5 of my set up book.
with what you wrote I understand balance and tweak are not the same thing at all.
